L.A.'s Nokia Theatre was the place to be on Sunday, Nov. 24. Music's biggest and brightest stars came together to honor one another at the 2013 American Music Awards, hosted by Mr. Worldwide himself, Pitbull.

Just when you think she couldn't possibly have any more tricks up her sleeve! Miley Cyrus closed out the 2013 AMAs with a powerful but strange rendition of "Wrecking Ball," featuring a giant hologram of a lip-synching cat floating in space.

After a powerful performance of her hit song "Diamonds," Rihanna was joined onstage by her mom, Monica, who presented the singer with the first-ever AMA Icon Award. "Rihanna, I'm so proud of you," the star's mother began, visibly emotional.

Some 18 years after "Waterfalls" climbed to the top of the charts, TLC's Tionne "T-Boz" Watkins and Rozonda "Chilli" Thomas reunited onstage to perform the song at the AMAs. They were joined by rapper Lil Mama, who filled the void left by the late Lisa "Left Eye" Lopes.

One week after her memorable stint on Saturday Night Live, Lady Gaga put her acting skills to use once again by role-playing with R. Kelly during a performance of "Do What U Want." Wearing a sparkly leotard and heels, the singer seduced her R&B duet partner with a sexy song-and-dance on a set made to look like the Oval Office of the White House.

5. Katy Perry Opens the AMAs WIth a Japanese-Inspired Performance of "Unconditionally"
